Compact 75% Layout with 81 Keys

The RK ROYAL KLUDGE M75 is a 75% mechanical keyboard with 81 keys in an Ocean Blue finish. It targets gamers, office workers and students who want a smaller footprint without losing the function row and navigation cluster. The gasket-mounted structure uses four layers of sound-absorbing material to reduce noise and vibration. Hot-swappable brown tactile switches come pre-installed and support both 3-pin and 5-pin replacements.

Hot-Swappable Switches and Wireless Pairing

Switches pull out with a standard switch puller so users can change feel without soldering. The keyboard connects via Bluetooth to laptops, PCs, smartphones and tablets, pairing with up to three devices at once. A rotary knob on the top right switches between paired devices, adjusts volume and powers the board on or off. An integrated OLED display shows battery level and the active connection mode. The 12.9 x 5.4 x 1.65 inch plastic case weighs 2.09 pounds and runs on an included AAA battery.

Users Who Want Tactile Feel and Multi-Device Control

This board suits typists who prefer a tactile bump, gamers who need RGB customisation through 18 dynamic modes and eight monochrome options, and multitaskers who switch between three Bluetooth hosts. Those needing a full-size layout with a dedicated number pad or a different switch characteristic will also need another model.

Questions about this item

How can I confirm the OLED smart display is showing the correct connection mode after I pair the keyboard?

The OLED smart display shows battery level, connection mode, and volume in real time, so the active Bluetooth channel or wired link appears immediately on the screen.

What comes in the box and do I need to purchase anything extra to start using it?

The package includes the M75 keyboard, one AAA battery, and the rotary knob is built in; no separate switch pack or keycap puller is required for basic operation.

Which version should I choose if I want a tactile feel without an audible click?

The brown switch model provides a tactile bump and quiet operation, making it the only version listed for a non-clicky mechanical feel.
